IMPROVEMENT IN HARVESTERS.

Specification forming part of Letters Patent No. 128,974, dated `Iuly16, 1872.

SPECIFICATION.

I, EZRA A. BECK, ofthe town of Sycamore, in'the county of De Kalb andState of Illinois, have invented certain new and useful Improvements inHarvesting-Machines, of which the following is a full description,reference being had to the accompanying4 drawing making a part of thisspecification, in which- Figure l is a plan view, the driving-wheelbeing represented in section; Fig. 2, an elevation, looking at theinside, with the plate C removed; Fig. 3, a detail; Fig. 4, aperspective, showingthe position of themachinewhen ready fortransportation from place to place 5 and Fig. 5, a perspective of themain frame and drivinggear removed from the wheel.

The drawing is on a scale of two inches to the foot.

My invention consists in certain improved devices for bringing themachine into suitable position to be transported from place to place andin the several devices and combinations herein claimed.

In the drawing, Arepresents the tread-band of the driving-wheel; B, thecasing, which may be made with and connected to the tread-band A, andforming a covering for the outside of the wheel, the hub to which theouter end of the axle D is secured 5 the other end of the axle revolvesin a bearing in the head L 5 C, a plate forming a covering for theinside of the wheel 5 E, the main frame, having two-arms, a a, in whichare eccentric holes, forming bearings for the eccentrics d d, which arepermanently secured to the collar o; through which the. axle D passes.'Io this collar, and upon the outside of G, is secured a lever, r, bymeans of which the collar c, and with it the eccentrics d, can berotated upon the axleD, changing the position of the main frame. s is asmall lever pivoted to the lever r, the lower` end of it being bent soas to enter holes or slots provided in the plate G, its object being tohold the lever r and collar fu, with the parts connected therewith, inany desired position; b b, two other arms,

'being part of the main frame, in the ends of which are bearings for theaxle c, upon which the beveled wheel I, with its pinion n, are secured 5e, a beveled pinion-wheel attached to a shaft passing through the lowerpart of the main frame E, upon the outer end of which shaft is the headwhich operates the pitmanrod, which is to be connected to the sickle inthe usual manner. g is a bar which passes through an opening in theplate C, and is permanently fastened to the main frame. The other end ofthis bar g is pivoted ath to the lower part of the standard N, which isconnected with the inner shoe M. The upper end of the standard N isprovided with a slotted head, L. The slot is provided with teeth. Asmall piece, l, which forms a bearing for the inner end of the axle' D,is also provided with teeth which engage with the teeth in the slot.This bearing Z may be provided with a permanent washer, indicated by adotted line in Fig. 3, and teeth may be provided in the side of theslottedV head, and on the inside of the washer, instead of as beforedescribed. By changing the position of the bearing l in the slotted headthe angle of the sickle-guards with the ground maybe somewhat changed.tis a loose collar upon the axle D, to which collar is secured a lever,J K. The arm K of this lever is bent at the outer end so as to passunder the pole P, which is pivoted to the machine by means of thecoupling-iron O and pin or rod n, one end of which is screwed into orotherwise secured to the main frame and the other supported by a bearingon the standard N, as shown in Fig. 45 G H, two wheels supporting theends of the sickle-bar F in the usual lnanner. When the machine is to betransported from place to place it can be brought into the positionshown in Fig. 4 by the use of the lever J K, as, by raising the arm J ofthe lever, the other end will lift the rear end of the pole, the end ofthe arm K passing gradually along the under side of the pole from theposition shown in Fig. 1 to that represented in Fig. 4, and may be heldin that position by a notch near the end of the pole. As the rear end ofthe pole is elevated by meanslof this lever J K the driving-wheelperforms a partial revolution backward, carrying with it the bar g. Atthe same time the sickle-bar is brought into nearly a vertical position,as shown ,in Fig. 4. On the inside of B are two sets of gear, Q It,between which the pinion upon the shaft c is located, as represented inFig. l. By means of the eccentrics d d I and lever r the position of themain frame and parts attached thereto can be changed, as before stated,bringing the pinion into gear either with the gearing Q or R, as may bedesired,

thus giving to the sickle either a rapid or slow motion, as may bedesired for different kinds of work. The pinion u is to be thrownentirely out of gear by stopping it between the gearwheels or gears Qand R, when the machine is to be transported from place to place. Sisthe drivers seat, so located as not to interfere with the properbalancing of the machine.

Among the advantages resulting from the construction described thefollowing may be mentioned: A single-wheel machine is furnished which isevenly balanced and which has a floating sickle-bar, this bar havingonly its own weight to support and being relieved from all strain fromthe weight of the machinery. A double-gear machine, simple inoonstruction, is provided. When the machine is transported thesickle-bar is brought into a vertical, or nearly vertical, position,relieving it trom the strain following from the ordinary construction.

What I claim as new is as follows:

1. The combination of the wheel A B with the frame E and face-plate C,provided with anY opening for operating the sickle at the side,substantially as described.

2. The inclosed main frame E provided with bearings a a, in combinationwith the eccentrics d d, pinion n, and gear Q, and a suitable device foroperating the eccentrics, substantially as and for the purposesspecified.

3. The notched head L on standard N, in combination with the notchedbearing Z, for the purpose of adjusting the angle of the guards,substantially as specified.

4. The lever J K, in combination with the hinged pole P, standard N,finger-bar F, and wheel H, for elevating the sickle, substantial- 1y asspecified. EZRA A. PECK.
